Modules for Backdrop CMS

TFA Rules is a Backdrop module that provides integration with the Rules module to
add a condition to check to see if TFA has been enabled for a user.

The purpose of this module is to avoid the situation where two people
are editing a single node at the same time. This module implements a
pessimistic locking strategy, which means that content will be
exclusively locked whenever a user starts editing it.

Enforce Revision Logs allows an administrator to force users to write a
revision log message whenever a revision is created. It can also force a
revision to be created for every modification.

This module is an API that other modules can use to encrypt data. It
doesn't provide any user-facing features of its own, aside from
administration pages to manage encryption profiles.

This module provides a way to encrypt field values when stored in the database.

Installation

The Blog module allows registered users to maintain an online journal, or blog. Blogs are made up of individual blog entries. By default, the blog entries are displayed by creation time in descending order, with comments enabled, and are promoted to the site's front page.

or unblocked. The module adds also two rules with that event.
